Paul yes the going rate seem's to be about £20, when i've looked on the net,Ebay, Amazon etc, i've looked at the digitutor one which is ok,i will take a look at the Thom hogan book, i just thought it would be good to have a DVD to watch on TV if you wanted to refer to something without having to turn on the PC, hope that make's sense.
Marcel, yes from what i've seen on the net blue crane do these tutorial's for a number of camera's, canon nikon etc..
